INVENTOR w. J P4770 ATTORNEY Patented Jan. 21, 1930 PATENT OFFICEWILLIAM J. PATTON, OF ST. LOUIS, MISSOURI ROAD-RESURFACING nnvronApplication filed December 9, 1927. Serial No. 238,904.

My invention relates to improvements in road resurfacing devices, and itconsists in the combinations, constructions, and arrangements hereindescribed and claimed.

An object of my invention is to provide a road resurfacing device whichis adapted to scrape the road sufficiently to remove the high portions,and which has novel means for smoothing or planing the road immediately0 following the scraping thereof.

A further object of my invention is to provide a device of the typedescribed which accomplishes a better result in a shorter time than thatwhich is ordinarily accomplished by two or more other devices which arenow used for producing a similar result.

A further object of my invention is to provide a device of the typedescribed in which .novel means is provided for increasing the rigidityof the cutting blade.

A further object of my invention is to provide a device of the typedescribed which will do the work more accurately than is done by theordinary device.

Other objects and advantages will appear in the following specification,and the novel features of the invention will be particularly pointed outin the appended claim.

My invention is illustrated in the accompanying drawings, forming partof this application, in which Figure 1 is a perspective view of my device, and

Figure 2 is an enlarged sectional view of my device.

In carrying out my invention, I provide a mold board 1 of a grader orplaner 2. A cuttingstrip 3 having a cutting edge A is rigidly secured tothe mold board 1.

An elongated shoe 5 having a flat planing surface 6 and a'rounded guidesurface 7 is provided with a slightly varcuate-shaped flange portion 8.The flange portion 8 is provided with a plurality of openings 9 whichare arranged to receive a plurality of bolts or rivets 10. The shoe 5may be secured to the mold board 1 and the cutting strip 3 by the bolts10.

From the foregoing description of the various parts of the device, theoperation thereof may be readily understood. The mold board may be movedin the usual manner for positioning the cutting edge 4: of the cuttingstrip 3 at a desired position relative to the surface of the road. Letus assume that the device is moved forwardly and in close engagementwith a road having an uneven surface. The cutting strip 3 will removethe high portions of the uneven surface of the road and dispose theloosened dirt in 50 the holes or lower portions of the road. As the dirtis disposed within the lower portions, the shoe 5 forces the looseneddirt within the holes and smooths the same. In this manner, the resultusually accomplished by a 05 scraper and a planer and perhaps a rolleris accomplished by the cutting strip 3 and the shoe 5 in one continuousoperation, the only difference being that the result accomplished by thestrip 3 and the shoe 5 is substantially better, owing to the fact thatthe two operations are done simultaneously, thus avoiding thepossibility of the result of one operation being affected before orduring another operation of the ordinary devices.

The connection of the shoe with the cutting strip aids both the shoe andthe cutting strip, as, for instance, considerable strain is applied tothe cutting strip and Without the aid of the shoe the cutting strip,together with the mold board, would vibrate as they are being drawnalong the road. The shoe 5 makes more rigid the cutting strip forholding the cutting strip against vibration, aided by its contact withthe road. Furthermore, the cutting strip 3 and the mold board 1 act as arigid support for the shoe, thus obviating the need of additionalapparatus for supporting the shoe.

Other advantages gained by the attachment of the shoe to the cuttingstrip are the preventing of the strip from dipping into the lowerportions of the road, and the making of a more accurate out.Furthermore, the shoe is so constructed that it will smooth or iron outthe road.

I claim:

A device of the type described comprising a mold board, a cutting striphaving a cutting edge, a planing shoe having an elongated road-engagingportion, a flange integral with said elongated portion and arranged tobe disposed in engagement with said cutting strip, said mold board, saidcutting strip, and said flange having a plurality of aligned openings,and means arranged to extend through the openings in said mold board,said cutting strip, and said flange for rigidly securing said cuttingstrip and said flange to said mold board.
